Gas Line Safety

Even in the DIY culture that prevails, gas line work remains taboo and that’s a very good thing. There are many home improvement projects and home repairs that can be taken on by amateurs but working on gas lines and appliances are definitely not one of them. The liabilities and chances for fires and explosions are simply too high to take the risk. 

In this article, you will learn exactly what a gas line is and where to find them in your home. You will also learn about protecting your home from the dangers of gas line leaks. 

Where Gas Lines Are Located In Your Home?

Understanding Gas Leaks and Prevention

Natural gas is one of the most popular utilities for heating in the US. Due to this, natural gas is always found in appliances that heat. Cooking stoves and ovens in your kitchen are powered by natural gas. Your hot water heater probably burns natural gas to provide you with hot water. Furnaces that heat homes are often powered by natural gas. Natural gas clothes dryers run more efficiently than their electric counterparts.

Since natural gas is so common in the home, the integrity of its plumbing is paramount. Leaks can occur in piping and are common in connections to gas-powered appliances. Steel gas lines are more subject to forming leaks than newer plastic-based piping. 

Causes Of Gas Leaks

Common Gas Leak Causes
Gas leaks are like water leaks in that they can occur at any point in your plumbing. The most common cause of gas leaks is the poor installation of gas-powered appliances. Most buildings still have steel gas lines that are threaded together. When appliances are installed, the threaded joints can loosen up or break their seek and begin to leak gas. Gas can also be corrosive to steel lines and allow seepage of gas after many years in use. 

Damage is another cause of gas line leaks. Gas lines are commonly damaged during digging projects like trenching or digging holes for fence posts.

Renovation projects can also leave gas lines vulnerable to damage or punctures as walls are demolished or rebuilt. 

Gas valves can be prone to leaking. Gas valves are located in all of your gas appliances. If the inside of the valves get damaged or fouled with debris, it can cause leaks. 

Preventing Gas Leaks In Your Home

Practicing good gas safety is critical for protecting your property. Some of the things you should look out for are:

  • Proper gas pressure: Gas pressure is regulated at your meter. Your gas company should set the proper pressure and check it to make sure the proper pressure is maintained. 
  • Gas line protection: Gas lines should be installed with a “dirt leg” that catches debris that may be in the gas. Debris can cause gas valves to fail and leak. 
  • Professional installation: Having a professional install your appliances is not just a good idea, it is usually required to take advantage of warranties and homeowner’s insurance.

Finally, the most important rule of gas safety: if you smell gas, ventilate the area by opening windows and leaving until a plumber can respond.
